#game instructions: scroll down and back sometimes to begin. click on canvas and play with keys Q/A for one player and L/P for the other. also works when seeing/executing all the tree parts/dweets d/14017 d/14016 and d/14015 . or just scroll my page up to the last part u/metamero

update: codegolf.tk (and all .tk domains), is permanently offline... for now there are a handful of working mirrors, e.g. https://whr.rf.gd/shorty/65NAW
